Netherlands and Germany via their study route. Schools are free so only need to cover your living expenses. If you're not getting a stipend from your supervisor then getting accepted to schools is far easier since your professor won't have to pay you (that's where you use your POF). See the steps below;
For Netherlands:
1. Get accepted to a school (probably a master's degree)
2. Finish it in 1.5 - 2 years
3. Use your prof's or school's network to find a job (all companies speak english, no need for dutch)
4. Work for 5 years
5. Apply for PR
For Germany:
1. Same as above
2. Same as above
3. Same as above
4. Learn B1 German:

In short, the level of German needed for permanent residency in Germany is B1, which is equivalent with being an intermediate learner. And work for 5 years.
5. Apply for PR
These are off the top of my head. Do you own research for other countries like Sweden, Finland etc. They have some pathways too. I remember that Switzerland is ridiculous like you need to work for 12 years that's just insane.
Pro tip: Be smart and try to find an industrial master's program for Step 3. That way you're literally working at a company while doing your research there = insta job offer after graduating.
Pro tip 2: Don't read the posts of clueless idiots who are blind to all these options around the world. They only (barely) know Canada. That's why they keep attacking me.
Pro tip 3: You can literally skip steps 1,2,3 if you apply to jobs on LinkedIn and get lucky enough to land a job in these countries. Quite a few of my friends have done it and I'm going for it too. If I can't land an offer I'll just use my POF and buy a degree then PR.
Note: It should be obvious but these EU study pathways only compare to Canada's study pathways. They're obviously not as fast or easy as FSW. If FSW dies in 2022, you're not limited to PGWP>CEC as you see. EU study pathways are far cheaper and more profitable than Canada's.
